The ClusterControl integrations allows you to integrate ClusterControl into any external application you are using for either communications or incident response management (e.g., Pagerduty, VictorOps, Telegram, Opsgenie and Slack). You do not have to worry about missing alerts.

In Galera Cluster, the gcache provides incremental state transfers by sending transactions to joining nodes. But if the gcache file is too small, this may cause full state snapshot transfers. The Galera replication window advisor will continuously review if your gcache size is large enough.

The new ClusterControl command line client allows easy integration with other automation and collaboration tools, such as chatbots. Instead of integrating the CLI in your own chatbot, you can use the Hubot based ClusterControl chatbot called CCBot alternatively.

Combining Galera and asynchronous replication in the same MariaDB setup, aka Hybrid Replication, can be useful as we’ve discussed previously. This new post takes things further and shows you how to deploy an asynchronous replication slave to MariaDB Galera Cluster 10.x (with master failover), using GTID with ClusterControl.

Hybrid replication, i.e. combining Galera and asynchronous MySQL replication in the same setup, became much easier since GTID got introduced in MySQL 5.6. In this blog post, we will show you how to replicate a Galera Cluster to a MySQL server with GTID, and how to failover the replication in case the master node fails.
